AIMIM president Asaduddin Owaisi today alleged that the 2007 Mecca Masjid blast case in which all the five accused facing trial were acquitted, had not been pursued properly by anti-terror investigative agency NIA.

Hyderabad Lok Sabha member Owaisi alleged on a micro-blogging site that most of the witnesses in the Mecca Masjid blast case had turned hostile after June 2014 and the NIA either didn't pursue the case as was expected from it or was not allowed by its political masters to do so.

Asserting that "justice hasn't been done in the case," Owassi said "questions would be raised over the criminal justice system (of the country) if such biased prosecutions continue."

The firebrand MP alleged that the Modi government did not even appeal against the bail given to the accused earlier.

"Justice has not been done, the NIA & the Modi govt didn't even appeal against the bail that was given to the accused within 90 days. This was a complete biased investigation which will weaken our resolve to fight terrorism," said Owaisi, recaling that nine persons had died and many more were injured in the 2007 blast.

A special NIA court here today acquitted five persons, including Swami Aseemanand, in the case. Nine persons had been killed and 58 injured in the blast.

Ten persons were named as accused in the case but only five of them were arrested and sent up for trial.
